What is a Titration

A titration is a technique where a solution of known concentration is used
to determine the concentration of an unknown solution. Typically, the titrant
(the know solution) is added from a buret to a known quantity of the analyte (the unknown solution) until the reaction
is complete. Knowing the volume of titrant added allows the determination
of the concentration of the unknown. Often, an indicator is used to usually
signal the end of the reaction, the endpoint.
